Republicans are ignorant.
“The election results reflect the decision of the right wing to cultivate and exploit ignorance in the citizenry. I suppose the good news is that fifty-five million Americans have evaded the ignorance-inducing machine. But fifty-eight million have not. . . . The error that progressives have consistently committed over the years is to underestimate the vitality of ignorance in America. Listen to what the red-state citizens say about themselves, the songs they write, and the sermons they flock to. They know who they are — they are full of original sin and they have a taste for violence.”
